This paper provides an overview of second language (L2) socialization research, some examples of recent studies addressing this topic, and finally a theoretical reconceptualization of L2 socialization. The three studies to be presented include secondary schools in an English-as-a-foreign-language context in Central Europe, mainstream classes in an English-as-a second-language school in Western Canada, and programs for English language and nursing skills for immigrant Canadians. This empirical, qualitative research does not support a linear, deterministic view of L2 socialization; such a view assumes, erroneously, that students or other novices are fully willing and able to adopt stable, monolingual, local target L2 norms and that members of the target culture are both competent and receptive to the newcomers. Some consequences and implications of these findings are discussed.

Over the years, the embryo transfer industry has grown from the simple collection & transfer of embryos into an advanced field of embryo biotechnology. Currently a large demand exists for bovine oocytes and early embryos in both research and commercial settings. Bovine embryos can now be produced in-vitro. Primary oocytes collected from antral follicles of abattoir - obtained ovaries can be induced to undergo the maturation process. In-vitor maturation system, however must ensure that the resulting oocyte is capable of undergoing normal fertilization and yields a zygote competent of developing to term after embryo transfer. Sperm preparation for IVF has improved with the use of heparine. The use of co-culture system has proved beneficial in circumventing the developmental block in IVM/IVF bovine embryos.

Library marketing is increasingly becoming a crucial part of library management as it allows libraries to analyze its customer base and their needs, develop library products and services customized to such needs, and actively promote those new developments to customers. To realize those steps, we need a competent marketing librarian. This study aims to define the role of marketing librarians and their required capacity to develop and execute effective library marketing strategies, and it also suggests training methods to foster marketing librarians.

To establish a competent method of microbiological assay for bacampicillin, one of new semi-synthetic derivatives of ${\beta}-lactam$ antibiotics, a comparison was carried out between different conditions for hydrolysis of bacampicillin into ampicillin which was then subjected to cylinder plate method. The results showed that the use of carboxylic ester hydrolase in vitro as a pretreatment of it in either pH value 6 or 8 was feasible and that the cylinder plate method with Sarcina lutea was adequate for potency estimation.

Genetic materials including DNA plasmid are effective delivery vehicle to express interesting gene efficiently and safely not to generate replication competent virus. Moreover, it has advantages to design a better vector and to simplify manufacturing and storage condition. To understand a possible pathogenic mechanism by a flavivirus, West Nile virus (WNV), WNV genome sequence was aligned to other pathogenic viral genome. Interestingly, WNV capsid (Cp) amino acid sequence has some homology to HIV-l Vpr protein. These proteins induce apoptosis in human cell lines as well as in vivo and cell cycle arrest. Therefore, DNA plasmid carrying apoptosis-inducing and cell cycle arresting viral proteins including a HIV-1 Vpr and a WNV Cp protein can be useful for anti-cancer therapeutic applications. This WNV Cp protein is an early expressed protein which can be a reasonable target antigen (Ag) for vaccine design. Immunization of a DNA construct encoding WNV Cp protein induces a strong Ag-specific humoral and Th1-type immune responses in animal. Therefore, DNA plasmid encoding apoptotic viral proteins can be useful tool for therapeutic and prophylactic applications.

PCR amplification with universal primer is a useful tool for speciation of symbionts in marine eukaryote coupled with robust separation method such as denaturing high performance chromatography (DHPLC). To overcome the biased amplification, clamping PCR is recommended to suppress the amplification of host gene. In this study, we evaluated the efficiency of rare gene detection for two kinds of clamping probes which were successfully utilized for eukaryotic symbiont analysis: C3 linked nucleotide (C3) and peptide nucleic acid (PNA). PNA was 3-4 orders of magnitude higher than that of C3 tested in clamping efficiency and rare gene detection. This represented that PNA could be a more competent clamping probe for the enhancement of PCR amplification for rare symbiont genes.

The suggestions that follow are about the Qualitative Improvement of private security Industrial. First, in legal and institutional policy, new establishment by law for private security and more support from government is asked. Moreover, the restructuring or M&A between petty companies and the pricing for security service should be performed. Second, in the structural aspect of private security industry, the professional education center for private security guards should be established and the terms of payment and welfare should be improved to the level above standard. In addition, it should be achieved to change the public to have a new and correct understanding of private security and develope the specialized parts suited to the characteristic and ability of each companies. Third, the construction of operating system for private security service should be achieved; recruit system for competent security guards, marketing strategy and enforcement system, widely known confidence to client, normal training system for security guards and post management system for client. This is also to be suited to the characteristic of each companies.

Information sharing and automated office in the use of PC necessitate corporate network to implement business innovation. Building an efficient network requires competent knowledge on capabilities of various LAN technologies, hardwares and softwares that have rapidly improved in terms of efficiency and cost. This paper compares capabilities of network components: communication protocol, hardware, network operation system, low cost database software and mid-range priced SQL for application development. Also this study presents a new technology on virtual LAN and a selection guide among the various options of the network components which are suitable for PC-based small-sized network in balance of efficiency with economy. In the last section of this paper, a case of small-sized network is given for illustration.

Although bulk metallic glasses have many outstanding aspects in their chemical, mechanical or functional properties, some critical problems still hinder their wide application. The most important one is the brittle nature of them, which is the serious problem to structural application. So, to use viscous flow is now the only competent way to form bulk metallic glass. In this study, we investigated the basic nature of viscous flow of Zr-base bulk metallic glass, vitrelloy 1, in terms of process variables. The results were used to design the thermo-mechanical process composed of heating, holding, pressing, and cooling, which have unique influence on the glass transition and crystallization behavior. We adopted small load scale and dies with nano/micro patterns on them. The results were evaluated using several analytical methods.
